I have driven my FGT in the rain, hail and snow a few times. Going to the FGT Rally in Vegas it rain and hailed pretty hard. I would agree that the car works great in the rain, but not in hail, those ice balls were like little ball bearings, you have very little steering control.
My main reason for saying the FGT isn't a good rain car is because of the other jokers out on the road. The chance of an accident are much higher, so I rather drive one of my disposable beater cars. Sam would say a BMW! :lol
Amen for Hail, which I somehow missed on the road to Austin. Freezing rain too.
Lousey drivers are everywhere, not weather dependant.
